I´m not sure if the engine was properly warmed up, i let the engine run some minutes, but will try it again but sometimes, the engine stop and doesn´t allow me to mantain the idle.
About the oxigen sensor, it needs to be a HEGO? (heated sensor), or could be an EGO?
how about this one?https://www.amazon.com/Bosch-13953-O...ct_top?ie=UTF8

About the EGR, I bought a new one, so I will replace it. I will do your test anyway, but if you say that it could not be the main cause of my problem...
I´m trying to find a correct TPS to replace it too!
Thanks!

yeah... fix the ones that are obviously broken, like the temp sensor, reset the codes, and see what comes back. It takes longer to fix things completely, but it will get done that way without just throwing parts and money at it.
